/** holds data provider key, description, and associated shared library file information

   The metadata class is used in a lazy load implementation in
   QgsProviderRegistry.  To save memory, data providers are only actually
   loaded via QLibrary calls if they're to be used.  (Though they're all
   iteratively loaded once to get their metadata information, and then
   unloaded when the QgsProviderRegistry is created.)  QgsProviderMetadata
   supplies enough information to be able to later load the associated shared
   library object.
